Abstract: This paper introduces an improved 3D-SPIHT algorithm. This algorithm can deal with the problems such as low efficiency when coding pictures with complex textures or many-sided pictures, large storage requirement and long time consumption, which are common to traditional 3D-SPIHT algorithm. The test shows that improved 3D-SPIHT algorithm can increase the compress ratio, save storage and time consumption, reduce the complexity of scanning codes. This algorithm avoids diamond effect and has a good performance.
